UNITED STATES JACOB JAHRAUS, OF

BUFFALO, NEW YORK.

IMPROVEMENT IN FAUCETS.

Specification forming part of Letters Patent No. 511,359, dated May l, 1866.

To all whom fit may concern:

Beit known that I, JACOB JAHRAUs, of the city of Buffalo, county ofErie, and State of New York, have invented a certain new and Improved Beer-Faucet 5 and I do hereby declare that the following is afull, clear, and exact description thereof', reference being had to the accompanying drawings, making a part of this specification, in which- Figure I is a vertical longitudinal' section of my said faucet. Fig. II is a cross-sectional elevation on line l 2. Fig. III' is a cross-section on line 3 4, and Fig. IV is a cross-section of key on line 5 6.

This invention relates to that class of beerfaucets which have small pumps or ejectors combined therewith, anditconsists in making the axis of the discharge-nozzle to coincide with that of the key, and placing therein vthe pump or ejector-barreh'its axis also coinciding with that of the key, in combination with a combined keyand plunger, thereby obtaining greater simplicity in construction and making the faucet capable of use either with or without the ejector.

A represents the stem of the faucet, the bore c of which terminates in the key chamber or socket.

B represents the key-chamber, the axis of which is at right angles, or nearly so, with the stem.

C represents the discharge-nozzle, which is an extension of the key-chamber, its axis coinciding with that of the key-chamber.

D represents the key, which for a short distance above and below the bore a of the stem, is made conical or tapering, the key-chamber having a corresponding taper, and the key being nicely fitted therein by grinding. The passage d through the key is extended downward at each end, as shown at d2, and communicates with the discharge-nozzle, so that when .the key is turned and its passage d brought in line with the bore of the f'aucet the liquor may pass downward into the discharge-nozzle.

E represents the pum p-barrel, which is placed within the discharge-nozzle, and concentric therewith. Itis smaller than the nozzle, so as to leave an annular space, e', through which the liquorvmay issue, this annular space being, in reality, the discharge-nozzle. It is secured l to the nozzle at the top and bottom by the feathers e2; j I

F represents a plunger' working in the pumpbarrel E, it being an extension of the key. The bottom of the pump-barrel is closed except a small perforatioin f. A button, f2, is placed a short distance Iabove the bottom of the barrel, and is secured thereto by a central stud. This button is slightly less in diameter than the bore of the barrel, so as to leave an annular space 4around it, the width of which space should be less than the diameter ot' the perforationf, so that anything which may pass the annular space will be sure to pass through this perforation, and the annular space, by its greater extent, will be less likely to become choked than the single perforation.

The key-chamber extends upward above the key, so that the key, and with it the plunger, may be raised sufficiently to withdraw the plunger from the pump-barrel. p The chamber is covered by a screw-cap, G, through which the key-stem D2 passes, said stem having a cross-handle,-D3, at its end, by which it may rloe readily raised or turned, as may be required.

The operation of this faucet may be briefly described as follows: When the cask to which the faucet is applied is full, and the beer fresh, the use of the ejector will not be required. In this case, by turning the key as in a common faucet, its passage d will be brought inline with the bore of the faucet, and the liquor allowed to how into and through the dishargeoriice e into the receiving-glass. After the beer has lost its freshness and it is desired to restore it by the use of the ejector, the faucet by raising instead of turning the key. The raising of the key will open a communication with the discharge-orice and allow the liquor to flow the same as by turning the key; but the plunger being withdrawn from the pumpbarrel by the act of raising the key, a portion of the liquor will ow into and till the pumpbarrel, so that when the faucet is shut by the descent of the key, theplunger will forcibly expel the liquor in the pump-barrel through the perforation f in its bottom into the glass, and the agitation of the beer in the glass caused by this injection will restore its lost iiavor and freshness.

must be opened in a different manner-that is,

The screw-capGflares outwardly around the key-stem, so as to forni a cup, g', which will catch and hold any liquor which may be carried up by the key-stem in raising until it shall have time to run back into the key-chamber y after the faucet is shut. If any liquor should remain in the key-chamber after the faucet is shut, the neXt upward .movement of the key would expel it around the stem through the chamber-cap. As a preventive of leakage at this place, in addition to the cup g', small holes l. Making the discharge-nozzle C an extension of the key-chamber B, and locating they pump-barrel E therein, in combination with the key D and plunger F, arranged and operating in the manner described.

2. Extending the key-passage d downward at each end thereof on the opposite sides of the discharge-nozzle extension of the key-chamber, as described.

3. Forming the key-chamber cap Gr with a cup, g', for the purpose set forth.

4. The holes h in the key, as set forth.

5. The combination of the button f2 with the perforation f', for the purpose set forth.
